Abstract (en)
[origin: FR2769113A1] The invention concerns an illuminated display device comprising a translucent element whereon are arranged displays, the translucent element being fixed, at least at one of its edges, to a frame (2) containing means (16) for emitting a light radiation into the thickness of the translucent element and through the edge thereof, the frame (2) comprising means (10) for powering the means (16) emitting light radiation. The invention is characterised in that the translucent element consists of two translucent panels (3A, 3B) comprising, on one (13A, 13B) of their surfaces (13A, 13B, 23A, 23B) printed zones with variable reflecting power, distributed according to a predetermined law ensuring a homogeneous distribution of the light emitted by the emitting means (16) in the entire translucent element, the two translucent panels (3A, 3B) being joined such that the surfaces (13A, 13B) provided with zones having variable reflecting power are in contact with each other, at least one of the two free surfaces (23A, 23B) of the jointed panels constituting a surface for arranging a display (7) to be illuminated.
